hello everybody
my new build system has suffered from repeated attack of BSOD and reboot randomly for several weeks already. I found the error message to be "Driver_IRQL_NOT_LESS_OR_EQUAL", bugcheck code to be 0x100000d1 (mostly) and 0x1000000a (one time).

The crash occurs mostly at bedtime when my computer runs merely a BT client (BitComet), but sometimes it crashes when I connectes the internet.

I've already had my computer scanned by NOD antivirus & PC-cillin online. It was reported to be virus-free; I've updated my drivers; I followed the protocol suggested in this forum and did a RAM check by Memtest86 and passed 32 cycles without error.

I have some minidump files(named by date of crashes), could someone please help me with this?

My computer spec: Intel CPU E6300+Asus P5LD2, nVidia 7300GT by Elsa, Transcend DDR-667 1GB (other details plz check my profile)
OS: Windows XP SP2
Suspected programs: BitComet, cFos7.04, Outpost firewall 4.0964, EasyRealMedia Producer 1.94

I think it could be your 8th slot. Onbaord ethernet.

Outpost Firewall is the problem. See HERE for the same problem.

BugCheck 100000D1, {ce0018, 2, 1, 7c931713}
PROCESS_NAME: svchost.exe
Probably caused by : Unknown_Image ( INVALID_CONTEXT )

Thank you for the kindeness of the answer.
I've dumped my outpost firewall and shifted to Comodo firewall.
Unfortunately, the crash recurred but this time turned to be "black screen"
and can't be waken after the sleep. So I think outpost may not be the sole cause of the crash.

Could someone help me to hijack the minidump?

Here's my new minidump file. I hope that would do some help.
I tried to hack by myself, however, it's a bit difficult for me do understand all the complicated information...:dead:

The outpost firewall is still in use. You haven't un-install outpost firewall.
